In modern society, traffic noise has become an important issue for mental health. A significant contributor to this noise pollution is exterior tyre/road noise, which is caused by the interaction between tyre and road surface and. In order to reduce tyre/road noise at the source, accurate numerical prediction models are needed. This research deals with the development of quantitative numerical models in order to simulate tyre/road noise. Tyre vibrations are calculated using a detailed three-dimensional finite element model of a tyre rolling on synthesized road surfaces in the time domain. The normal velocity on the tyre surface is interpolated from a rotating to a fixed mesh and transformed to the frequency domain. Tyre/road noise is calculated by means of a sound radiation model using boundary elements. For the experimental validation, a device has been developed by which tyre/road noise can be measured on a moving car. The simulated tyre/road noise of a slick tyre rolling on various road surfaces at different speeds has been compared to the measurements. Although the simulations predict higher noise levels than the measurements, the trends are in good agreement. From a computational point of view, solving a contact problem, like the tyre/road contact, is one of the major challenges. A new contact algorithm has been developed which, in principle, can be used solve contact problems fast using multigrid. Characteristic is that the contact condition is always satisfied, so there is no need for contact elements or contact parameters.
